Points are just easier to work with. You don't have to worry about
the complexities of closing meshes and such. You could probably make
a decent point model just from a 2d image of someone. Doing that
with
meshes is a hassle.
Also, 3d laser scanning translates more naturally into point clouds.
Plus, points are closer to how it is in the real world.
